URGENT PLEASE HELP 98 POINTS Find the direction angle of vector v to the nearest tenth of a degree.

zlopas [31]

Answer:

The direction angle of vector v is equal to $9.5\°$

Step-by-step explanation:

Let

$A(-5,0),B(7,2)$

The vector v is given by

$v=B-A$

$v=(7, 2) - (-5, 0)$

$v=((7 - (- 5)), (2-0))$

$v=(12, 2)$

Remember that

The direction angle of the vector is equal to

$tan (\theta) =\frac{y}{x}$

substitute the values

$tan (\theta) =\frac{2}{12}$

$\theta=arctan(\frac{2}{12})=9.5\°$

A cable car can safely carry n people thete are alreafy 3/4n people on the cable car only 12 more people can board the cable car

ipn [44]

Answer: 48 people.

Step-by-step explanation:

1. You know that $n$ represents tha number of people that the cable car can safely carry.

2. If you know that there are $\frac{3}{4}n$ and only 12 more people can board it before it becomes unsafe, you can write the following expression:

$n=\frac{3}{4}n+12$

3. Now, you must solve for $n$ .

4. Then, the number of people that the cable car safely carry is:

$n-\frac{3}{4}n=12\\\frac{1}{4}n=12\\n=12*4\\n=48$

25% of 400 is equal to 20% of What?

Bess [88]

Here is your answer:

First find 25% of 400:

400/x=100/25
(400/x)*x=
(100/25)*x
x 400=4*
400/4=x
100=x
x=100

The answer is "500."

100 ÷ 20%
100 ÷ (20 ÷ 100) =
(100 × 100) ÷ 20 =
10,000 ÷ 20 =
= 500

Hope this helps!
